Work out what would happen if a grounded pith ball came near the electroscope. Draw where the charges would be. Try this out, making sure the pith ball doesn’t touch the electroscope. Now work out what would happen if the pith ball touched the electroscope. Let the pith ball bounce against the electroscope, and then draw the charges to show why it acts differently (or should act differently) at this point.
SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question 1) There is a 5.0 uC charge at each of 3 comers of a square (each side 70. mm long). What is the force on +6.0 µC placed at the center of the square? 1) 2) How far apart should two protons be if the electrical force of repulsion is equal to the weight (attraction to the Earth) of one of the protons? 2) FIGURE 15-6 2.5m 2.5m 0.5m 3) Two volleyballs, each of mass 0.300 kg, are charged by an electrostatic generator. Each is 3) attached to an identical string and suspended from the same point, as shown in Fig. 15-6. They repel each other and hang with separation 50.0 cm. The length of the string from the point of support to the center of a ball is 250. cm. Determine the charge on each ball. 4) Charge +2q is placed at the origin and charge -q is placed at x = 2a. Where can a third positive charge +q be placed so that the force on it is zero?
